Rise of the machines

Industrial robots are dangerous machines that can easily kill a person.

Most have to be surrounded by protective fencing, flashing lights and warning signs.

Compared with such hazardous machinery, the Kuka LBR iiwa is like a cuddly toy. It is one of a new generation of small robots that can work alongside humans on highly sensitive tasks.

The LBR iiwa — or “lightweight robot” and “intelligent industrial work assistant” — is a super-flexible machine with seven joints that can twist round like human wrists and elbows. It also has sensors to detect whether people or obstacles are in its path: if they are, it slows down or stops.

What is most striking about the iiwa is its sensitivity. “It can screw, install, insert — and all with feeling,” says Christina Heckl, a Kuka engineer.

The iiwa is part of the company’s attempt to break out of the confines of the factory and produce robots that can work in other environments like hospitals and, ultimately, the home.

“It’s a very exciting time,” says Ms. Heckl. “Now that we have such sensitive robots we can develop completely new applications for them.”

Till Reuter, Kuka’s chief executive, sees robots playing an ever larger role in people’s lives. Care for the elderly is a huge potential application. “It is not just about increasing efficiency but making life easier for people and keeping them active,” he says.

Mr. Reuter says Günther Oettinger, the EU digital commissioner, once asked him if Kuka could design a robot to take him to his friends to play cards when he’s old.

But the Kuka boss is equally interested in more mundane household tasks.

“A robot that picked up socks would be good,” he says.
